FIG. 6.

Calculated XANES spectra for the Ti L_2,3 edge of SrTiO₃ (red, solid line) compared to experimental data (blue, dotted line) and a multiplet calculation⁴⁴ (green, dashed line). Due to the close spacing of the edges the full MPSE was not included. Instead, the imaginary part of the self-energy was applied by aligning the onset with respect to each edge and including a core-hole lifetime (0.10 eV and 0.24 eV), shifting between the two at 461.5 eV. This lifetime broadening also neglects solid-state Coster-Kronig and phonon effects.
